PILOT-BEAM.

Specification of Letters Patent.

Application filed January 30, 1913. Serial No. 745,184.

To all whom it may concern:

Be it known that I, EDMUND P. KIyNE, a citizen of the United States, and resident of Alliance, in the county of Stark and State of Ohio, have invented certain new therewith.

The pilot endsof locomotives particularly such locomotives as are used in switching and freight service, receive a large share of the stresses due to the fact that cars are attached to either end of the locomotive as occasion requires. It thus follows that the bcam,-or end casting which carries the usual coupler, is subjected to severe strains both in pulling and bufiing which strains, if not properly applied, lessen the stability of the engine and damage the front trucks and the king-bolt connection to the en ine saddle.

I have designed and show in the accompanying drawings, a pilot beam which is extremely rigid, which connects directly with the king-bolt and which provides for a 'very necessary addition to the ordinary equipment, a draft rigging housing. In connection with the draft rigging housing (I have arranged for the application of the .rigging and coupler shank from the face of the beam. This is essential in view of the fact that the rigging could not be applied from beneath as is common to frei ht cars. This is accomplished by the use .0 a very rigid U-shaped key the two legs of which, when the ke is in place, project from the inside latera edges of the draw-bar opening and prevent the withdrawal of the draft rigging without removal of the key.

It will be understood that the car coupler is suitably connected to the draft rigging, 45 the U-shaped key being contacted b the edges of the front follower of the dra t riging. The specific construction referred to shown in my co-pending application, Serial No. 735,226.

The. invention will be more readily understood by reference to the accompanying drawings, wherein Figure l is a plan view of a pilot beam constructed in accordance with my-inven- 55 tion; Fig. 2 is a section on the line 2-2 of rearward Fig. l, and Fig. 3 is a front elevation with the ends of the beam broken away.

Referring more particularly to the drawings it will be seen that the construction includes a cross beam 10, which maybe of any desired configuration but is preferably hollow as shown. Projecting rearwardly from this beam is an integral structure 11, hav- Patented Sept. 2, 1913.

ing transverse strengthening ribs 1%, dii agonal ribs 13 and marginal ribs or flanges 14. A king-bolt opening 15, properly reinforced, extends through the "structure 11,

and provides for the connection of the beam v to the engine truck and saddle. Formed within the end beam 10 and the rearwardly projecting structure 11, is a recess 16, the only entrance to which is through the face of the beam 10. Surrounding the opening to the recess 16 is a body of metal 17, 18, 18 at the top and sides thereof. A vertical opening 19 15 Provided to the rear of the rib 17, this openin extending throughout the height of the cam 10 and forming oppositely facing grooves 20, shown in Fig. 2. Vithin these grooves I may mount a U-shaped key'having depending legs 21 and a to cross bar 22, the cross bar lying behind tli arranged thatit is extremely rigid, provision is made for the accommodation of a draft gear and the shank of a coupler, and

the beam is directly connected through the king-bolt to the frame of the engine, The parts are suitabl ribbed and reinforced as required and as ound necessary in practice.

Although the structure is shown as one integral casting, it will be understood that portions of the end beam may be formed separately, and united b riveting or bolting if found necessary or esirable. Also, that other modifications may be made all of which are within the spirit of my invention.
